Not an important question, more a curiosity.
I've created an object in Maya, after that I deleted all the history, freeze all transformations, center the pivot and triangulated it, and exported as an .obj.

When I import that same object into Realflow, the gizmo doesn't appear centered in the object but centered in the middle of the grid.

I don't use Maya Vitor, but I'm curious. When you build your object in Maya and it's not built around the origin, even though you centre the pivot in the object, does the pivot appear in RF where your origin was in Maya?

This may be a question for the plugin developers, so post a new thread in the Maya forum with reference to the plugin and link it to this thread.
